• Loading a DB table into nested dictionaries in Python

  - by Hossein

  Hi, I have a table in MySql DB which I want to load it to a dictionary in python. the table columns is as follows: id,url,tag,tagCount tagCount is the number of times that a tag has been repeated for a certain url. So in that case I need a nested dictionary, in other words a dictionary of dictionary, to load this table. Because each url have several tags for which there are different tagCounts.the code that I used is this:( the whole table is about 22,000 records ) cursor.execute( ''' SELECT url,tag,tagCount FROM wtp ''') urlTagCount = cursor.fetchall() d = defaultdict(defaultdict) for url,tag,tagCount in urlTagCount: d[url][tag]=tagCount print d first of all I want to know if this is correct.. and if it is why it takes so much time? Is there any faster solutions? I am loading this table into memory to have fast access to get rid of the hassle of slow database operations, but with this slow speed it has become a bottleneck itself, it is even much slower than DB access. and anyone help? thanks

• Which libappmenu.so must I edit under GTK 3.0 to remove Eclipse from the HUD blacklist?

  - by JacobusR

  Under GTK 2.10.0 one could allow HUD for Eclipse by replacing Eclipse with Xclipse in: /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so After doing an update, this file dissapeared from the GTK 2.10 and now I'm guessing I should do the same edit in: /usr/lib/gtk-3.0/3.0.0/menuproxies/libappmenu.so Only problem is that there is no such file ;-) I did find a similarly named file: /usr/lib/indicators/7/libappmenu.so But don't know if that is the right place to mess with it. If anyone has an updated answer for enabling the heads up display (cool menu at the top) for Eclipse under the latest Ubuntu 12.10 will you kindly share it?

• problem in decreasing page's queries

  - by Mac Taylor

  hey guys i have a tag table in my php/mysql project that looks like this Table name : bt_tags Table fileds : tid,tag and for every story rows there is a filed named : tags Table name: stories table filed : tags that saved in this field as ids 1 5 6 space between them now problem : when using while loop to fetch all fields in story table , the page uses 1 query to show every stories' detail but for showing tag's names , i should query another table to find names , we have ids stored in story table now i used for loop between while loop to show tag names but im sure there is a better way to decrease page queries how can i improve this script and show tag's names without using *for loop ?* $result = $db->sql_query("SELECT * FROM ".STORY_TABLE." "); while ($row = $db->sql_fetchrow($result)) { //fetching other $vars ---- $tags_id = explode(" ",$row['tags']); $c = count($tags_id); for($i=1;$i<$c-1;$i++){ list($tag_name,$slug) = $db->sql_fetchrow($db->sql_query( 'SELECT `tag`,`slug` FROM `bt_tags` WHERE `tid` = "'.tags_id[$i].'" LIMIT 1' )); $sow_tags = '$tag_name,'; }

  I'm following the instructions at: http://agilewebdevelopment.com/plugins/acts_as_taggable_on_steroids to add the tag cloud to my view: in the controller: class PostController < ApplicationController def tag_cloud @tags = Post.tag_counts end end I also added the tag_cloud method as a helper method in the controller and in the view: <% tag_cloud @tags, %w(css1 css2 css3 css4) do |tag, css_class| %> (line 1) <%= link_to tag.name, { :action => :tag, :id => tag.name }, :class => css_class %> (line2) <% end %> (line 3) However: 1) if I don't add the helper_method :tag_cloud in the controller I get a undefined method error for tag_cloud 2) if I do add the helper method I get: wrong number of arguments (2 for 0) on the same line 1 of my sample code above.

• Mongodb, simple IN problem

  - by afvasd

  Hi everyone I am new to mongo, this is my db design: product := { name: str group: ref, comments: [ ref, ref, ref, ref ] } comments := { ... a bunch of comments stuff } tag := { _id: int, #Need this for online requests tag: str, products: [ {product: ref, score: float}, ... ], comments: [ {comment: ref, score: float}, ...], } So my usage pattern is: GIVEN a product, find comments that have certain tag and sort them accordingly. My current approach involves: Look for that tag object that has tag=myTag pull all the comments out, sorted look for that product where product.name=myProduct pull all the comments out (which are dbrefs by the way) loop through the result of 2, and checking if they are in 4, (this I can do a limit 10) etc. It's pretty inefficient. Any better methods?

• Rails Routes Mappings

  - by rdasxy

  I'm a rails newbie, and I have a controller called resource_links that I've mapped to resources: resources :resources, :as => :resource_links, :controller => :resource_links And this works (basically /resources works as /resource_links). However, trying to go to /resources/tags does not work. To get around this, I added more mappings as: match 'resource_links/tag/:tag(.:format)' => 'resource_links#tag', :via => :get, :as => 'resource_links_tagged', :constraints => {:tag => /.*/} match 'resource_links/tags' => 'resource_links#tags', :via => :get, :as => 'resource_links_tags' Is there any way I can get /resources/tags to be mapped to /resource_links/tag?

• Playing HTML5 Video with fall back for IE8/IE7 and earlier versions of other browsers using Silverlight

  - by Harish Ranganathan

  One of the popular HTML5 tags is the video tag.  The ability to play videos without depending on a plugin is something that excites web developers to a great extent and no wonder you end up seeing video demos in all HTML5 conferences. Now, coming to HTML5 Video, the tag itself is simply <video id=”ID” src=”FILENAME.mp4/ogv/webm” > in the simplest form.  This also means that the video needs to be H.256 encoded MP4 format or some of the other formats as mentioned above.  For a detailed specification on this, check this Wikipedia article HTML5 video is supported by all the modern browsers such as IE9 (currently in RC stage), Mozilla Firefox 4 and Chrome latest versions.  Here below is a simple example of a HTML5 video tag and the screen shot of how it looks like in IE9 RC <!DOCTYPE html> <head></head> <body> <h1>This is a sample of an HTML5 Video</h1> <video src="video.mp4" id="myvideo">Your browser doesn’t support this currently</video> </body> </html> You can add attributes to the video tag such as “autoplay” which will automatically start playing the video.  Also, you can specify “poster” to display an initial picture before the video starts playing etc., but I am not going into those for now. This would play well in the modern browsers as mentioned above.  However, if the end users are viewing this page from an earlier version of browsers such as IE8/IE7 or IE6, this video wouldn’t play.  Whatever text that is specified between the video tags, would just show up. Note: for demo purposes, I went to the IE9 developer toolbar and chose IE8 as Browser Mode to exhibit this legacy behaviour.  However, in the interest of serving the larger community of users who visit the site, we would like to have a fall back mechanism for playing videos on older version of browsers. Now, Silverlight is supported in IE6/7 & 8 and other browsers too.  If we can have the same video encoded for Silverlight, we can put the fall-back code, as follows:- <video src="videos/video.mp4" id="myvideo">     <object height="252" type="application/x-silverlight-2" width="448">         <param name="source" value="resources/player.xap">         <param name="initParams" value="deferredLoad=true, duration=0, m=http://localhost/DemoSite/videos/video.mp4, autostart=false, autohide=true, showembed=true, postid=0" />         <param name="background" value="#00FFFFFF" />     </object> </video>   Note, this sample uses a Silverlight XAP file with the same video and uses the object tag to embed it instead of the HTML5 video tag. So, when I now run this sample and switch to IE8 (using the IE9 Developer toolbar’s Browser Mode), I get and when clicking on the “Play” icon, Note, there are multiple ways to play videos in Silverlight and this is one of the ways.  For a complete list of Silverlight samples, visit http://www.silverlight.net/learn/  Also, we can use Flash to play video in the fall-back mechanism as well. Thus, we can create a fall-back mechanism for playing HTML5 videos for the older browsers and hence ensure that the end users get to experience the same. Cheers !!!

  - by Jon

  I cant get my wifi card to work at all after upgrading to 11.10 Oneiric. I'm not sure where to start to fix this. Ive tried using the additional drivers tool but this shows that no additional drivers are needed. Before my upgrade I had a drivers working for the Rt2860 chipset. Any help on this would be much appreciated.... thanks Jon jon@ubuntu:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:1d:72:ec:76:d5 inet addr:192.168.1.134 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21d:72ff:feec:76d5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7846 errors:0 dropped:0 overruns:0 frame:0 TX packets:7213 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8046624 (8.0 MB) TX bytes:1329442 (1.3 MB) Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:91 errors:0 dropped:0 overruns:0 frame:0 TX packets:91 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:34497 (34.4 KB) TX bytes:34497 (34.4 KB) Ive included by dmesg output below [ 0.428818] NET: Registered protocol family 2 [ 0.429003] IP route cache hash table entries: 131072 (order: 8, 1048576 bytes) [ 0.430562] TCP established hash table entries: 524288 (order: 11, 8388608 bytes) [ 0.436614] TCP bind hash table entries: 65536 (order: 8, 1048576 bytes) [ 0.437409] TCP: Hash tables configured (established 524288 bind 65536) [ 0.437412] TCP reno registered [ 0.437431] UDP hash table entries: 2048 (order: 4, 65536 bytes) [ 0.437482] UDP-Lite hash table entries: 2048 (order: 4, 65536 bytes) [ 0.437678] NET: Registered protocol family 1 [ 0.437705] pci 0000:00:02.0: Boot video device [ 0.437892] PCI: CLS 64 bytes, default 64 [ 0.437916] Simple Boot Flag at 0x57 set to 0x1 [ 0.438294] audit: initializing netlink socket (disabled) [ 0.438309] type=2000 audit(1319243447.432:1): initialized [ 0.440763] Freeing initrd memory: 13416k freed [ 0.468362] HugeTLB registered 2 MB page size, pre-allocated 0 pages [ 0.488192] VFS: Disk quotas dquot_6.5.2 [ 0.488254] Dquot-cache hash table entries: 512 (order 0, 4096 bytes) [ 0.488888] fuse init (API version 7.16) [ 0.488985] msgmni has been set to 5890 [ 0.489381] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 253) [ 0.489413] io scheduler noop registered [ 0.489415] io scheduler deadline registered [ 0.489460] io scheduler cfq registered (default) [ 0.489583] pcieport 0000:00:1c.0: setting latency timer to 64 [ 0.489633] pcieport 0000:00:1c.0: irq 40 for MSI/MSI-X [ 0.489699] pcieport 0000:00:1c.1: setting latency timer to 64 [ 0.489741] pcieport 0000:00:1c.1: irq 41 for MSI/MSI-X [ 0.489800] pcieport 0000:00:1c.2: setting latency timer to 64 [ 0.489841] pcieport 0000:00:1c.2: irq 42 for MSI/MSI-X [ 0.489904] pcieport 0000:00:1c.3: setting latency timer to 64 [ 0.489944] pcieport 0000:00:1c.3: irq 43 for MSI/MSI-X [ 0.490006] pcieport 0000:00:1c.4: setting latency timer to 64 [ 0.490047] pcieport 0000:00:1c.4: irq 44 for MSI/MSI-X [ 0.490126] pci_hotplug: PCI Hot Plug PCI Core version: 0.5 [ 0.490149] pciehp: PCI Express Hot Plug Controller Driver version: 0.4 [ 0.490196] intel_idle: MWAIT substates: 0x1110 [ 0.490198] intel_idle: does not run on family 6 model 15 [ 0.491240] ACPI: Deprecated procfs I/F for AC is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared [ 0.493473] ACPI: AC Adapter [ADP1] (on-line) [ 0.493590] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input0 [ 0.496771] ACPI: Lid Switch [LID0] [ 0.496818] input: Sleep Button as /devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input1 [ 0.496823] ACPI: Sleep Button [SLPB] [ 0.496865] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 [ 0.496869] ACPI: Power Button [PWRF] [ 0.496900] ACPI: acpi_idle registered with cpuidle [ 0.498719] Monitor-Mwait will be used to enter C-1 state [ 0.498753] Monitor-Mwait will be used to enter C-2 state [ 0.498761] Marking TSC unstable due to TSC halts in idle [ 0.517627] thermal LNXTHERM:00: registered as thermal_zone0 [ 0.517630] ACPI: Thermal Zone [TZS0] (67 C) [ 0.524796] thermal LNXTHERM:01: registered as thermal_zone1 [ 0.524799] ACPI: Thermal Zone [TZS1] (67 C) [ 0.524823] ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared [ 0.524852] ERST: Table is not found!

• Android RestTemplate Ok on emulator but fails on real device

  - by Hossein

  I'm using spring RestTemplate and it works perfect on emulator but if I run my app on real device I get HttpMessageNotWritableException ............ nested exception is java.net.SocketException: Broken pipe Here is some lines of my code(keep in mind my app works perfect on emulator) ............ LoggerUtil.logToFile(TAG, "url is [" + url + "]"); LoggerUtil.logToFile(TAG, "NetworkInfo - " + connectivityManager.getActiveNetworkInfo()); ResponseEntity<T> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, clazz); ............. I know my device's network works perfect because all other applications on my device are working and also using device browser I'm able to connect to my server so my server is available. My server is up and running and my device is able to connect to my server so why I get java.net.SocketException: Broken pipe ?!!!!!!! Before I call restTemplate.exchange() I log NetworkInfo and it looks ok -type: WIFI -status: CONNECTED/CONNECTED -isAvailable: true Thanks in advance. Update: It is really weird Even if I use HttpURLConnection, it works perfectly on emulator but on real device I get 400 Bad Request Here is my code HttpURLConnection con = null; try { String url = ....; LoggerUtil.logToFile(TAG, "url [" + url + "]" ); con = (HttpURLConnection) new URL(url).openConnection(); con.setRequestMethod("POST"); con.setRequestProperty("Connection", "Keep-Alive"); con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); con.connect(); LoggerUtil.logToFile(TAG, "con.getResponseCode is " + con.getResponseCode()); LoggerUtil.logToFile(TAG, "con.getResponseMessage is " + con.getResponseMessage()); } catch(Throwable t){ LoggerUtil.logToFile(TAG, "*** failed [" + t + "]" ); } in log file I see con.getResponseCode is 400 con.getResponseMessage is Bad Request

• Java how can I add an accented "e" to a string?

  - by behrk2

  Hello, With the help of tucuxi from the existing post Java remove HTML from String without regular expressions I have built a method that will parse out any basic HTML tags from a string. Sometimes, however, the original string contains html hexadecimal characters like é (which is an accented e). I have started to add functionality which will translate these escaped characters into real characters. You're probably asking: Why not use regular expressions? Or a third party library? Unfortunately I cannot, as I am developing on a BlackBerry platform which does not support regular expressions and I have never been able to successfully add a third party library to my project. So, I have gotten to the point where any é is replaced with "e". My question now is, how do I add an actual 'accented e' to a string? Here is my code: public static String removeHTML(String synopsis) { char[] cs = synopsis.toCharArray(); String sb = new String(); boolean tag = false; for (int i = 0; i < cs.length; i++) { switch (cs[i]) { case '<': if (!tag) { tag = true; break; } case '>': if (tag) { tag = false; break; } case '&': char[] copyTo = new char[7]; System.arraycopy(cs, i, copyTo, 0, 7); String result = new String(copyTo); if (result.equals("&#x00E9")) { sb += "e"; } i += 7; break; default: if (!tag) sb += cs[i]; } } return sb.toString(); } Thanks!

  Im working on an image sharing site and want to implement tagging for the images. I've read Questions #20856 and #2504150 I have few concerns with the approach on the questions above. First of all it looks easy to link an image to a tag. However getting images by tag relation is not as easy. Not easy because you will have to get the image-to-tag relation from one table and then make a big query with a bunch of OR statements( one OR for every image). Before i even research the tagging topic i started testing the following method: This tables as examples: Table: Image Columns: ItemID, Title, Tags Table: Tag Columns: TagID, Name The Tags column in the Image table takes a string with multiple tagID from the Tag table enclosed by dashes(-). For example: -65-25-105- Links an image with the TagID 65,25 and 105. With this method i find it easier to get images by tag as i can get the TagID with one query and get all the images with another simple query like: SELECT * FROM Image WHERE Tags LIKE %-65-% So if i use this method for tagging, How effective this is? Is querying by LIKE %-65-% a slow process? What problems can i face in the future?

• Django: Odd mark_safe behaviour?

  - by Mark

  I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior. The "call stack" looks like this: class Input(Widget): def render(self): return html_tag('input', attrs={'type':self.itype, 'id':self.id, 'name':self.name, 'value':self.value, 'class':self.itype}) class Field: def __unicode__(self): return mark_safe(self.widget.render()) And then {{myfield}} is in the template. So it does get mark_safed'd twice, which I thought might have been the problem, but I tried removing that too..... I really have no idea what's causing this, but it's not too hard to work around, so I guess I won't fret about it.

• template engine implementation

  - by qwerty

  I am currently building this small template engine. It takes a string containing the template in parameter, and a dictionary of "tags,values" to fill in the template. In the engine, I have no idea of the tags that will be in the template and the ones that won't. I am currently iterating (foreach) on the dictionnary, parsing my string that I have put in a string builder, and replacing the tags in the template by their corresponding value. Is there a more efficient/convenient way of doing this? I know the main drawback here is that the stringbuilder is parsed everytime entirely for each tag, which is quite bad... (I am also checking, though not included in the sample, after the process that my template does not contain any tag anymore. They are all formated in the same way: @@tag@@) //Dictionary<string, string> tagsValueCorrespondence; //string template; StringBuilder outputBuilder = new StringBuilder(template); foreach (string tag in tagsValueCorrespondence.Keys) { outputBuilder.Replace(tag, tagsValueCorrespondence[tag]); } template = outputBuilder.ToString(); Responses: @Marc: string template = "Some @@foobar@@ text in a @@bar@@ template"; StringDictionary data = new StringDictionary(); data.Add("foo", "value1"); data.Add("bar", "value2"); data.Add("foo2bar", "value3"); Output: "Some text in a value2 template" instead of: "Some @@foobar@@ text in a value2 template"

• Making HABTM relationships unique in CakePHP

  - by Andrea

  I have two models, called Book and Tag, which are in a HABTM relationship. I want a couple (book, tag) to be saved only once. In my models I have var $hasAndBelongsToMany = array( 'Tag' => array( 'className' => 'Tag', 'joinTable' => 'books_tags', 'foreignKey' => 'book_id', 'associationForeignKey' => 'tag_id', 'unique' => true ) ); and viceversa, but the Unique flag does not help me; I can still save two times the same couple. How do I do this in CakePHP? Should I declare the couple (book, tag) unique in the database directly, or will this make CakePHP go nuts? Is there a Cakey way to handle this situation? EDIT: I tried making the couple unique with the query (I'm using MySQL) ALTER TABLE books_tags ADD UNIQUE (book_id,tag_id); but this does not work well. When I save more than one tag at a time, everything goes well if all the couples are new. If at least one of the couples is repeated, CakePHP fails to do the whole operation, so it does not save ANY new couple (not even the good ones).

• SQL INSTR() using CSV. Need exact match rather than part

  - by Alastair Pitts

  This is a follow up issue relating to the answer for http://stackoverflow.com/questions/2445029/sql-placeholder-in-where-in-issue-inserted-strings-fail Quick background: We have a SQL query that uses a placeholder value to accept a string, which represents a unique tag/id. Usually, this is only a single tag, but we needed the ability to use a csv string for multiple tags, returning a combined result. In the answer we received from the vendor, they suggested the use of the INSTR function, ala: select * from pitotal where tag IN (SELECT tag from pipoint WHERE INSTR(?, tag) <> 0) and time between 'y' and 't' This works perfectly well 99% of the time, the issue is when the tag is also a subset of 2 parts of the CSV string. Eg the placeholder value is: 'northdom,southdom,eastdom,westdom' and possible tags include: north or northdom What happens, as north is a subset of northdom, is that the two tags are return instead of just northdom, which is actually what we want. I'm not strong on SQL so I couldn't work out how to set it as exact, or split the csv string, so help would be appreciated. Is there a way to split the csv string or make it look for an exact match?

• Component returned failure code: 0x80600011 [nsIXSLTProcessorObsolete.transformDocument]

  - by Sean Ochoa

  So, I'm using the XSLT plugin for JQuery, and here's my code: function AddPlotcardEventHandlers(){ // some code } function reportError(exception){ alert(exception.constructor.name + " Exception: " + ((exception.name) ? exception.name : "[unknown name]") + " - " + exception.message); } function GetPlotcards(){ $("#content").xslt("../xml/plotcards.xml","../xslt/plotcards.xsl", AddPlotcardEventHandlers,reportError); } Here's the modified jquery plugin. I say that its modified because I've added callbacks for success and error handling. /* * jquery.xslt.js * * Copyright (c) 2005-2008 Johann Burkard (<mailto:[email protected]>) * <http://eaio.com> * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

• Several xml errors using Facebook JS SDK with xhtml strict

  - by Landitus

  I'm trying to set up some like buttons to a project. These buttons live inside a jquery slideshow with Aino's Galleria and let you "Like" each different slide. I'm using an xHTML strict document and while in Firefox (and Firebug) everything seems ok, but in webkit inspector I get this: XML self-closing tag syntax used on <fb:like>. The tag will not be closed. [The HTML that caused this error was generated by a script.] XML self-closing tag syntax used on <fb:like>. The tag will not be closed. I get one of these every slide, so there are 28 errors. Looking into it, found some seem to enclose the fb:like into something like this: <script type="text/javascript"> //<![CDATA[ document.write('<fb:like href="<?php echo "http://www.site/image-".$image_id ;?>" width="260" height="80" show_faces="false" />'); //]]> </script> The above, still works in Firefox, but not in Safari. The inspector says: 26 XFBML tags failed to render in 30000ms. Moreover, for the Facebook like buttons to work with the Galleria Jquery plugin, I have a custom function that reloads only the facebook like button concerning the actual slide which appears briefly upon loading the slide: [...] extend: function(options) { // listen to when an image is shown this.bind(Galleria.IMAGE, function(e) { number = e.index + 1; tag = $('.galleria-info-description .info-box-'+number).find('.btn_fb'); $(tag).each(function() { FB.XFBML.parse( this ); }); }); } This thing is getting more complex and really don't know who is causing the problem! Hope somebody can help or ask the right questions!
